Ever wanted to save your all items from lava like you now can with your Netherite tools? Look no further! The Netherited mod adds the Fireproof enchantment which prevents any item that falls into lava or touches fire from disappearing. In versions for 1.18+, Shulker Boxes can be enchanted with Fireproof and retain the enchantment.

To get a Fireproof Enchanted Book just place a book, a Netherite ingot, and a Netherite Upgrade in the Smithing Table. After getting it, apply it to any item you want with an anvil.

Shulker boxes can be enchanted with Fireproof, and keep the enchantment when placed and broken.
